The URIResolver handles URIs appearing at the XSLT level, the EntityResolver
does the same for URIs appearing at the XML level. In your command line you
set both; in your Java application you have set the URIResolver but not the
EntityResolver.

To set an EntityResolver from a Java application, you need to create a
SAXSource rather than a stream source, to instantiate your own XMLReader
(the SAX parser), set the EntityResolver on the XMLReader, and then do
saxSource.setXMLReader().

> The catalog resolver sucessfully initialises.. i get the :
